WILLIAI P, WALSH, OF CHICAGO, ILLINOIS.

NONREFILLABLE BOTTLE.

Application filed September 8, 1921.

To all whom it may concern:

Be it known that WILLIAM P. WVALsH, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, has invented new and useful Improvements in Nonrefillable Bottles, of which the following isa. specification.

The object of the invention is to provide means for use in conjunction with a bottle or other receptacle that will prevent its refilling after having been initially filled and the contents dispensed. To attain this object the receptacle is provided with a flaring mouth and a stopper seated in said mouth and capable of being initially locked therein but irremovable without destruction of the mouth of the receptacle.

The invention is illustrated and constructed in a specific embodiment to which, however, it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.

In the accompanying drawin Figure 1 is a view partly in eldvation and partly in section showing a receptacle equipped with the improved stopper.

Figure 2 is a transverse horizontal sectio-nal view on the line indicated by 2-2 of Figure 1.

Figure 3 is a perspective view of the locking medium by which the stopper is retained in the mouth or neck of the receptacle.

The invention is susceptible of use with a jug or any suitable receptacle but is shown in use in connection with a bottle 1 formed with a contracted neck 2 and a flaring mouth 3 terminating in an annular flange 4. The periphery of the mouth is formed with a circumferential slot in which there engages the spring washer 5, the latter also engaging in a slot 6 formed in the stopper 7, the latter conforming in shape to the shape of the mouth and being provided at its upper end with a protruding neck or discharge spout 8 exteriorly threaded at its terminus for the reception of a cap 9 between which and the extremity of the discharge spout there is interposied a gasket 10. The cap 9 serves as aclosure to exclude dustor any foreign substances from the discharge spout, the stopper 7 is bored from the under face in alignment with the openin through the discharge spout and is externafiy threaded to receive Specification of Letters Patent.

the plug 11 which is formed with an axial bore and provided with a valve seat at the upper end of which the ball valve 12 may engage, the walls of the bore. converging to the bore in the discharge spout. A nib or lug 13 is disposed at the point of juncture of the converging walls of the bore with the discharge spout and this lug is for the purpose of preventing the valve, when the receptacle is upturned, from closing the bore in the discharge spout. Pin seats 14 are provided in the bottom end of the plug for engagement with the pins of a spanner wrench to enable the attachmentot the plug in the stopper.

The bottle 1 is initially filled before the attachment of the stopper 7 but after the filling operation is completed, the stopper is attached in place or sealed which operates and. necessitates the attachment of the ring to the stopper in the peripheral groove 6. As the stopper is inserted the beveled edge 15 of the locking ring bears on the converging side walls of the mouth and the ring is compressed until the stopper is fully seated, when the ring reaches the peripheral groove in the mouth and expands, thus locking the stopper in place as clearly indicated in Figures 1 and 2.

Having described the invention, what is claimed as new and useful is 1. In a device for the purpose indicated, the combination with a receptacle provided with a flaring mouth, of a stopper of a shape corresponding with that of the mouth, and means for irremovably locking the stopper in the mouth, the stopper having a valve controlled discharge opening termed there through.

2. in a device for the purpose indicated, the combination with a receptacle and a stopper therefor, of means for irremovably locking the. stopper in the mouth of the recep tacle, the stopper being formed with a discharge opening therethrough, a valve enclosed within the stopper and controlling the discharge opening to close the same in one position of the receptacle and open the said discharge opening in another position of the receptacle, and a removable closure carried by the stop-per at the extremity of the discharge opening. 7

3. The combination with a receptacle and stopper therefor, of means for irremovably lockmg the stopper in the mouth of said receptacle, the stopperbeing formed with a discharge spout and formed with a bore axially aligned with saiddischarge spout but of greater diameter than the bore of the latter, a plug inserted in said bore, said plug ally aligned with said discharge spout but of greater diameter than the boreof the latter, a plug inserted in said bore, said plug itself being formed with a bore and having a valve seat at its upper end, the walls of the bore converging to the walls of the bore in the discharge spout, and a valve removably seated on the upper end of said plug, the stopper being formed with a projecting lug partially obstructing the bore through said discharge spout to preclude the valve .closing the same during the discharging operation of the receptacle.

In testimony whereof he afiixes his signature.

WILLIAM P. WALSH.
